Figure 5From: Automatic segmentation of deep intracerebral electrodes in computed tomography scans An example of the behaviour of the algorithm in the Electrode Axis Estimation step. (a)This panel represents the result of the algorithm, i.e., the axis (r H,D ) and each axis point, A k , computed at each iteration, while the other three figures represent the steps executed at each iteration: (b) represent the computation of a point s, on the line connecting the two previous computed axis points, A k−1 and A k−2, with distance d from the point A k−1; (c) is the computation of a point q 0 that it is the point with the higher intensity value in “cubic” region R centered in s; (d) represent the computation of the axis point A k , i.e., the center of mass of a region R centered in q 0.Back to article page
